Lacula Oil Company Limited, a wholly owned subsidiary of ROC, has provided an update on activity at the Cabinda Onshore South Block, Angola.
The Castanha-1 exploration well that commenced drilling on November 13, 2009 has reached Total Depth of 3,400 mBRT. The well encountered a gross hydrocarbon column of approximately 15 meters (between 2,214 mBRT and 2,229 mBRT) in the pre-salt section. Wireline testing recovered oil (estimated to be approximately 33° API) from this interval and preparations are under way to production test the well.
The Coco-1 extended well test that commenced in November 2009 has been completed and the well suspended. Results indicate that none of the five zones tested exhibited natural hydrocarbon flow. The testing equipment has been re-directed to the Castanha-1 exploration well. Depending on the success of the planned production testing at Castanha-1, Joint Venture participants will review the results from the Coco-1 extended well test and its future potential.
